Has anyone out there installed one of those "performance chips" in their Maxima? I've got an 07 Maxima and I ordered one of those chips but the instructions are so vague and generic as to be almost useless. I'm afraid to take a chance without better information. The instructions say to mount the chip (resistor) across the two terminals that go to the IAT sensor, but they don't say which two pins (there are more than just two wires on that connector). I bought a Nissan service manual and it looks like the sensor is across pins 5 and 6 but I'm still concerned....
